The present invention relates to improvements yin guide flanges for railway vehicles, and has for an object to provide animproved guide flange that will be noiseless in operation.

The metal flanges now quit generally usedon railway vehicle wheels have the disadvantages of being noisy and of wearing out quickly. It is the purpose of the present invention todo away with l these disadvantages.

In accordance with the invention, the guide flange carries an anti-vibrating material presented to the rail head to avoid the contact of metal to metal, thereby eliminating noise, and at the same time, such material is replaceable, whereby the anti-,vibrating substances may be replaced `with comparatively small expense without having to replace the entire guide flange.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointedout in the claims appended hereto.

In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure l is a transverse section taken through a portion of a rail head and Vehicle wheel showing an improved kguide flange constructed according to the present invention.

Figures 2, 3 and 4 are fragmentary-vertical sections of modified forms of guide flanges.

Referring more vparticularly to the drawing, I designates apneumatic tire, such for instance as employed on rail cars, which pneumatictire yis mounted upon a rim 2, having a guide flange'S` extending outwardly therefrom along one side of the tire and adapted to cooperate with the rail head 4 to maintain the vehicle on the track.

This guide iiange 3 carries at its outer portion, which projects beyond the perimeter of the tire I, a body of some anti-vibrating material 5, such for example as ebonite, hard rubber, bakelite, hardwood, etc. Such materials as ebonite, hard rubber, bakelite and some other substances are mouldable, and when fluid orplastic, may be poured or moulded into a recess or cavity provided inthe guide iiange. This cavity is shown to be embraced between innerand outer wallsk II and I2, which are `preferably undercut inr order to `give the body 5 of the anti-vibrating material a firm purchase'and an interlocking engagement Vwith the rail flange. The body of material 5 thus becomes a moulded ring extending about thewheel, and in position to engage the rail head 4.

The exposed face a of the ring or body of material 5 is adapted to come into contact with the (ci. zes- 7) lateral face b of therailll, and in so doing noises and vibration are diminished and eliminated.

The body of material 5 will project out beyond I the cavity, so as to permit contact with the rail head without allowing any part of the guide flange to cause a metal to metalcontact.

Referring more particularly to Figure 2,A the n body 5a of anti-vibrating or sound deadening material is held in place by an inner removable wall or flange I la, bolted, riveted, or otherwise secured,

as indicated at l, to the guide iiange 3a. The outer wall I 2a may be permanent, as in Figure 1.`

In accordance withvthis Figure 2, an organic material like hardwood,A which is not subjectto pouring and moulding, may be used and may be cut and shaped to t the cavity or recess and put in place after the removable wall IIa hasbeen removed. This wall IIfL is subsequently replaced.

andfastened to the guide flange 3a, thus securely holding the organic ring y5a in place. The inner Wall IIa may be circular and extend all about the inner side of the substance 5a. Its removal facilitates the replacement ofthe ring 5a when l worn. A

Referring more particularly to Figure 3, in this example, the guide flange 3b is devoid of" any recess or cavity and may be simply made plain. The sound deadening material or lsubstance 5b may be simplyv placed against the plane surface` `substance or ring 5 is contained in ak recess or cavity formed in a detachable member 9, and such detachable memberis removably secured to the guide flange 3C, as by the `use rof bolts, or other fastening means'lll. In this case, the sound deadening material 'will be moulded into the cavity in the member 9.

It will be apparent that with the use of lthe invention, silence will attend the movement of lthe guide :flange upon the side of the rail head.

Moreover, the substance 5 will, besidehaving` head.

With the ordinary railway wheel, when the guide flange is worn, the entire wheel must be replaced, but with the use of the present invention, in the event of wear, it is only necessary to replace the substance or ring 5, or, in the case of Figure 4, themember 9 carrying the substance 5C. The remainder of the guide flange is retained and is not subject to wear or deterioration.

It will be obvious that various changes in the construs. combination and enana-nut e! parts cinllsinbly 1mdk which couldhe umd 'ithout departing from the spirit of my invention, and I do not mean to limit the invention to Smil details except as particularly pointed out in the claims.

Having thus described my imwlmtinnf-r what: 1 claim and desire to secure kauwen mld the United States is:-

1. In a railway vehicle wheel, a guide ange therefor having a recess disposed in the side thereof facing the rail, and a sound deadening materia-l seated in said recess'and projecting beyond in position to engage the rail, a portion at least of the side walls of said recess being removable.

2. Il a rdlw'y vehicle wheel, a guide iiange sklni'lrt, ilumina an outer overhanging Wall, a. ring of sound deadening material placed glinst said flange and said wall, and a removable wall engaged with the guide flange and with a atlieevist*r of said sound deadening ring.
